On April 19, 2019, while driving his car, he killed a woman and her child, who were on a bicycle, and injured nine pedestrians in what is called the Higashi-Ikebukuro runaway car crash. Following the crash, special treatment of him by the police, legal system and media, due to his privileged position in society, drew much attention and criticism.
